Problem with Login Script after update to 3.6.7 pl1

[Mac_Cross]

Hi Guys,
I use this login script on a board with the 3.6.5 version. It's working without any problems. After the upgrade to the 3.6.7 version i have the problem that the script doesn't work anymore. But I cant find the mistake. Does anyone can help me?

PHP Code:

    require_once('global.php');
    require_once('includes/functions_bigthree.php');
    require_once('includes/functions_login.php');

$cookieuser=0;
    
    
        $vbulletin->input->clean_array_gpc('p', array(
            'vb_login_username' => TYPE_STR,
            'vb_login_password' => TYPE_STR,
            'vb_login_md5password' => TYPE_STR,
            'vb_login_md5password_utf' => TYPE_STR,
            'postvars' => TYPE_STR,
            'cookieuser' => TYPE_BOOL,
            'logintype' => TYPE_STR,
            'cssprefs' => TYPE_STR,
        ));
    
        // can the user login?
        $strikes = verify_strike_status($results->fields[nickname]);
    
        if ($results->fields[nickname] == '')
        {
            eval(standard_error(fetch_error('badlogin', $vbulletin->options['bburl'], $vbulletin->session->vars['sessionurl'], $strikes)));
        }
    
        if (!verify_authentication($results->fields[nickname], $results->fields[passwort], $vbulletin->GPC['vb_login_md5password'], $vbulletin->GPC['vb_login_md5password_utf'], $cookieuser, true))
        {
            ($hook = vBulletinHook::fetch_hook('login_failure')) ? eval($hook) : false;
    
            // check password
            exec_strike_user($vbulletin->userinfo['username']);
    
            if ($vbulletin->GPC['logintype'] === 'cplogin' OR $vbulletin->GPC['logintype'] === 'modcplogin')
            {
                // log this error if attempting to access the control panel
                require_once(DIR . '/includes/functions_log_error.php');
                log_vbulletin_error($results->fields[nickname], 'security');
            }
            $vbulletin->userinfo = array(
                'userid' => 0,
                'usergroupid' => 1
            );
    
            if ($vbulletin->options['usestrikesystem'])
            {
                eval(standard_error(fetch_error('badlogin_strikes', $vbulletin->options['bburl'], $vbulletin->session->vars['sessionurl'], $strikes)));
            }
            else
            {
                eval(standard_error(fetch_error('badlogin', $vbulletin->options['bburl'], $vbulletin->session->vars['sessionurl'])));
            }
        }
    
        exec_unstrike_user($results->fields[nickname]);
    
        // create new session
        process_new_login($vbulletin->GPC['logintype'], $cookieuser, $vbulletin->GPC['cssprefs']);
    
        // do redirect
        do_login_redirect();
